BED-SPRING.

To all whom it may concern:

Be it known that I, JAMES H. Drn'i'r, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Bed-Springs, of which the following is a specification.

This invention relates to bed springs and has for its object to provide a bed spring, especially of the kind having a woven wire bed bottom fabric, with a reinforcement or support which will give stability to 'the middle portion of the spring and prevent it from sag ing, and which will also act to prevent t e mattress from sliding out of place on the bed spring and from becoming sunken or depressed. j

To this end the spring fabric is provided longitudinally thereof substantially midway between its side edges with an elastic reinforcement consisting, preferably, of a large wire rope cable inclosed within a pocket in the spring fabric which `forms a sort of central rib or 'back bone on the spring.

In the accompanying drawings:

Figure 1 is a broken plan view of a bed spring embodying the invention.

Fig. 2 is a fragmentary cross section thereof, on an enlarged scale.

Fig. 3 is a fragmentary longitudinal section thereof, on an enlarged scale, on line 3 3, Fig. 1. v

The bed spring comprises, as usual, a bottom fabric A attached at its ends to the end bars b of a frame B which may be of any usual or suitable construction. The bottom fabric shown is of the well known woven wire formation and is provided with wire rope edges C, such as are employed on some bed springs.

D represents a strip of woven wire fabric similar to the bed spring fabric A which extends lengthwise of the spring midway between its side edges. The side edges of this strip are attached to the spring fabric, as by interlacing the edge coils of the strip D with adjacentv coils d of the s ring fabric thereby formingl a central ongitudinal pocket on the spring fabric. Throu h this pocket extends a reinforcing rope or e ement Specication of Letters Iatent.

E, preferably similar to the edge ropes C of the spring. The ends of the pocket strip D and rope E are attached to the end bars of the spring frame, as by means of the securing strips e for the bottom fabric.

The rope E and inclosing pocket con-V structed as described produce a longitudinal reinforcement for the bottom fabric which projects upwardly and downwardly beyond the top and bottom surfaces of the fabric, as clearly shown in Fig. 2. This back bone or rib-like projection is adapted to sink into the mattress to an extent such that it acts to revent theY mattress from sliding or shi ing out of lace on the bed spring. The projection of) the rib is not, however,

Y suliciently pronounced to be objectionable to the feeling in the use of the bed.

The reinforcement not only strengthens the bed spring centrally in a vertical direction so as to'prevent it from sagging in the middle, but it also prevents the depression extending longitudinally between the side edges of the bottom fabric and having upper and lower walls at the Vupper and under sides of the bed bottom, and an elastic ex-v tensible rope extending through said pocket and attached at its ends to said frame, said rope holding the walls of said pocket apart and causing said pocket to bulge upwardly thereby forming a longitudinal upwardly projecting rib on the bed bottom.
